Sunbelt Environmental Services began as a branch office of Sunbelt Industrial Services, which was headquartered in Fort Worth, Texas. The Springfield branch opened in 1986, operated by Leroy Schaefer. The Missouri Corporation of Sunbelt Environmental Services, Inc. was created in 1993 under the ownership of Leroy Schaefer and Tom Underwood. In 2013, the company was purchased in full by Leroy and Karen Schaefer.

Sunbelt Environmental Services owes its success to its employees, including President Larry Smalley, who has been with the company since 1987. The staff of environmental professionals continues to be the cornerstone of Sunbelt’s ongoing success and growth.
